Determining Transmission Port in a Gpon Network

1. A method for operating an ONT in a GPON architecture, the method including: receiving a DHCP response message; processing said response message comprising: determining a port-id identified in the DHCP response message; and determining an upstream transmission port-id from the port-id identified in the DHCP response message; generating a service filter that associates the upstream transmission port-id with at least one address; applying said service filter to an upstream transmission comprising: determining an address identified in the upstream transmission; and determining an upstream port-id associated with the identified address; and transmitting the upstream transmission on a port identified by the upstream port-id.

2. The method according to claim 1 wherein processing said response message includes determining at least one of a source address and a destination address and wherein said filter is dependent on at least one of a determined source address or a determined destination address.

3. The method according to claim 2 wherein the destination address includes a network address and subnet mask and the filter is dependent on said network address and subnet mask.

4. The method according to claim 2 wherein the source address includes a CPE address.

5. The method according to claim 1 wherein producing said service filter includes associating a virtual local area network with an address identified in said DHCP response message.

6. The method according to claim 5 wherein applying said filter includes determining an address in said at least one upstream data transmission and determining a virtual local area network associated with said address.

7. The method according to claim 1 wherein the method is deployed in at least one of a following per service architecture: VLAN; IPsec; GRE; IP in IP; and MPLS.

8. The method according to claim 1 wherein the method is deployed in at least one of a following per subscriber architecture: VLAN; IPsec; GRE; IP in IP; and MPLS.

9. The method according to claim 1 wherein processing the DHCP response message is performed in an optical network termination.

10. The method according to claim 1 wherein an expiration of a service filter is linked to an expiration of an IP address provided in said DHCP response message.

11. A gigabit passive optical network including: at least one optical line termination; at least one optical network termination in communication with said at least one optical line communication through a plurality of ports; and at least one virtual local area network; wherein the at least one optical network termination includes at least one filter for determining an upstream port-id on which to provide an upstream transmission to said at least one optical line termination, said at least one filter being created by determining the upstream port-id from a port-id identified in a DHCP message produced by the at least one virtual local area network, said at least one filter used to determine a destination address of the upstream transmission, and used to further determine an upstream port-id associated with the identified upstream address and transmit the upstream transmission on a port identified by the upstream port-id.

12. The optical network according to claim 11 including at least one virtual local area network per service.

13. The optical network according to claim 11 wherein the at least one optical network termination is configured to process said DHCP message to produce said at least one filter automatically.

14. A non-transitory computer readable storage medium comprising at least one set of instructions executable on at least one processor, the at least one set of instructions including instructions for: receiving a DHCP response message; processing said response message comprising: determining a port-id identified in the DHCP response message, and determining an upstream transmission port-id from the port-id identified in the DHCP response message generating a service filter that associates the upstream transmission port-id with at least one address; applying said service filter to an upstream transmission comprising: determining an address identified in the upstream transmission, and determining an upstream port-id associated with the identified address, and transmitting the upstream transmission on a port identified by the upstream port-id.

15. The non-transitory computer readable storage medium according to claim 14 including instructions for determining the destination address.

16. The non-transitory computer readable storage medium according to claim 15 wherein the destination address includes a network address and subnet mask.

17. The non-transitory computer readable storage medium according to claim 14 including instructions for associating a virtual local area network with an address identified in said DHCP response message.

18. The non-transitory computer readable storage medium according to claim 17 including instructions for determining an address in said at least one upstream data transmission and determining a virtual local area network associated with said address.

19. The non-transitory computer readable storage medium according to claim 14 wherein the instructions are executable on at least one processor of an optical termination unit of a gigabit passive optical network.
